hey! i took some help from a friend and they told me to use this code, but my issue with thise code is that only the first frame is loaded properly and the rest when loaded are loaded as zeros and not with the numbers in the original text frame. My frames are 2D with just a ton of numbers and there are 3000 of them, how do i fix this issue?
Matrix=zeros(156,207,3000);
for i = 1:3000
Matrix(:,:,1)=load(['frames_' num2str(i-1) '.txt']);
end

@tina: you changed the original indexing into a 1, which is why you only store the first frame.
N = 3000;
M = nan(156,207,N);
for ii = 1:N
F = sprintf('frames_%d.txt',ii-1);
M(:,:,ii) = readmatrix(F);
end % ^^ compare this indexing
